I specifically given you the answer regarding your very own power supply in attempt to possibly fix you very own problem.
While I have did not tested three 7950 before, I had used three 7970 (to be exact, I had during that time) on a 1050w unit a few months back with some friends. To be exact, the XFX ProSeries 1050w unit, which is based off of your very own Seasonic. I too had shut downs, in which just switching around the cables made it work. However, the only time we had problems was during heavy overclocks under water cooling during benching scenarios, which the OP said he will not be overclocking his GPUs.Edited by qwan456 - 7/3/13 at 10:46am
